Reason
- As observed from the animation for all the 6 Iteration runs it can be seen that in the First 3 Runs, elements can be seen cracking away and then being deleted from the animation.
- It means to tell that Law 2 (PLAS_JOHNS) materials are more realistic.
- Keeping Dadv=Ixfem=1 shows cracking more significantly.
- Material in LAW 1 and LAW 36 are exceeding UTS of 425 MPa which is unrealistic.
- Result Files of all the 6 Iteration run will be attached.
